A source said: ‘They wanted to ensure it was just the two of them and everything was kept as quiet as possible.

‘They did it in complete secrecy — even most of their friends and family had no idea they were going there to get married.

‘By keeping everything a closely guarded secret, they pulled it off and surprised their loved ones. Naturally, everyone is delighted.’

While the pair met on the hit BBC show in 2014, it wasn’t until the following year – when Rachel announced she had split from her husband of 16 months James Gilbert – that they went public with their romance.
